IMPROVEMENT IN THE MANUFACTURE OF PASTEBOARD.

Specification forming part of Letters Patent No. 87,407, dated March 2, 1869; anteda'ted October To all whom it may concern Be it known that I, W-LLLIAM E. HALE, of the city of Chicago, county of (look, and State of Illinois, have invented new and useful Im-' provements in Lining Straw-Board and Other Thick Paper; and I -do hereby declare that the following is a full, clear, and exact descriptionof the same, which will enable others skilled in the art to make and use the same, reference beinghadto the accompanying drawings, in which- Figure 1 is a longitudinal section of my inventiojn'taken in theline sew, Fig. 2, and Fig. 2 is atop or plan view of the same.

' Similar letters of reference indicate like parts.

Myin'ven tion has for its object to cover-continuous sheets of binders board as it is made on the machine-with continuous strips of thin white or other paper. Hitherto such boardhas been made in sheets and'covered or lined with thin paper by hand. By my improved method the, board can be made and covered in one strip of any desired length at -one opera tion, thereby avoiding the necessity of first making the board in comparatively small sheets and then covering it by hand, as in the ordinary manner. The papercan, moreox-"er,

be laid upon the board with greater regularity, as both are pressed evenly together at all 1 points as they pass through the machine.

The invention consists, first, in covering binders board with continuous strips of thin paper and, second,- inthe construction of the mochine for producing this result. i t

In the drawings, Arepresents a frame or box adapted to be arranged in a convenient posh tion over the drying-cylinders of an ordinary paper or straw board machine. The box is of versely in the compartment 0 containing a quantity of paste. From'the roll E the paper receives a coating of paste, and passes thence to the straw-board or heavy paper d, which is fed to the drying-cylinders of the paper-machine-by any suitable mechanism. The lining of the box A. The rollers F may'also serve as drawing-rollers for the paper I), the tension of thelatter being regulated by the vweight and cord, e passing over. the friction-roller f, affixed outside the'frame to the journal of the roller. D. The method of regulating the-tension of the paper is, however, immaterial. The covered orlined board; after leaving the rollers F F is conducted to the drying-cylinders "of the paper-machine, uponwhich it is thoronghly'dried preparatory to being used. 11' represents a horizontal scraper adj nsted in the paste-compartment O by means of the screws 9 pin the partition 'a, to regulate the quantity of past-etc be suppliedto the lining by the roller E.

From the above descriptionit will be'readily understood that the straw or other thick paper will be lined in the most complete and efl'ective manner, and with great rapidity and economy.

Having thus described my invention, what I claim as new, and desire-to secure by Letters Patent, is-

1. Lining continuous strips of straw or other WILLIAM HALE.
